1,391,814., f ff citizen of the United UNITED STATES PATENT oFFlcs.- L l HARRY E. '.WoLFE, or HAsTINGs, MICHIGAN@ COMBINATION FoUNnRY-Toon To all whom it may' concern Be it known that I HARRY Ej WoLrE, a gtates of America, and resident of Hastings, in the countycf Barry and State of Michigan, have invented certain new and useful" Improvements in Combination Foundry-Tools, ofwhich the following is a specification. y

This invention relates .to combination tools, and particularly to a combined shovel and tamping device, the saidinvention being j orimarily'forjuse in foundries where sand is to be delivered to molds and the sand is to be tamped, as in the molding operation.

An object of'this invention is to provide a novel tamping attachment having adjustable features which permit the tampingdevice to be used edgewise or fiat for peening sand rvalong the sides of themold or for tamping it in the middle thereof.

f A further object-,of this invention iis to produce a tamping device capable of being held in one position of adjustment and then released to assume another position where it will operate ina different manner from that in which it operatedin the first position.

A still further Aobject of this invention is to produce an attachment for shovel handles in which the adjustment may be readilyV attained, and having a securing device which will positively retain the parts in one position of adjustment.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, `and in which- Y i v Figure 1 illustrates a view in elevation of a shovel, showing the device embodying the invention partly in section, applied-thereto;

Fig. 2 illustrates an edge elevation of the supplemental handle;

Fig. 3 illustrates a central sectional view thereof; j

Fig. 4 illustrates a perspective view of a locking device; and l Fig. 5 illustrates a perspective view of an element coacting therewith.

In these drawings, 10 denotes a shovel and ll a handle, which ,may be of any ordinary Y has an elongated yrotation with relation to the pivot.

Va rivet, andthe saidjsupplemental handle Ychannel 15 Y preferably l g closed by aface plate 16, the said channel constituting a seat in which the latch 17 is slidable. The latch 17 has a rod 18 connected to its inner end, and the said rod eX- tends outwardly, as shown' at 19, through a slot'20 and terminates in a thumb piece 21 which may be pressed to retract the latch 17 against the action of a spring 22 which encircles the rod 18 between the inner end of the latch and an abutment `23 which acts as a guidefor the rod and as a limiting Velement for holding the spring under compression. The outer` end of the handle terminates in arms 24 and 25 between which a pivot or pintle 26 extends, and the said arms 24 and 25 have lugs 27 and 28 respectively, which engage the tamping head 29 to limit the swinging movement of the head in one direction, it being shown in the drawing that the side lof the tamping head has rethe lugs, and theedge of the said tamping head has an opening or recess 31 in which the end vof the latch projects. The latch cessed portions such as 30 forming seats for prevents the movement of the tamping head n in one direction and the lugs engaging the side of the tamping head prevent it from moving in the opposite direction, and hence, so long as the latch is lying in the recess 31 of the tamping head, the tamping head will be held against movement.

The tamping head furthermore has one edge 32 of a contour which will prove effective in packing sand around the edges of a mold, but when the tamping head is released and extends across the end of the handle as shown in dotted lines (Fig. 3), the effective area is relatively large and hence, sand in the middle of a mold may be tamped expeditiously.

In order to rotatably mount the tamping head on the pivot 26, a bushing 35 is inserted in a tubular portion 34 of the tamping l head and the ktamping head rotates on the bushing, and the said bushing is held against The bushing 35 is rotatably mounted on the pivot but it has a lug 36 which locks into a recess 37 in the arm 24 of the handle.

A spring 38 has one end anchored to the rbushing 33 another end anchored, to the bushing 35, and hence, when the tamping head swings with relation to the pivot 26 to the position shown in- Fig. Vl, the spring is wound and is under tension when the lug 36 is applied to the arm 24. When the bushing 35 is moved axially of the pivot andV the lug-36 disengages from the arm 24, the spring will prove efective to swing the tamping head to the dotted line position shown in Fig. 3, when the device will be operative to form a butt which will be used. iny ramming the top of the mold, and when f Jfurther handling the shovel, it comes natural to return the tampmg head to the position` flat side 33 which lits against a correspondingiat side of the tube, in order that the tube and bushing 33 may rotate together on the pintle 26, and it is by reason of the fact that the bushing 35 is held stationary while the bushing 33 is being rotated, that the spring 3S is wound.

I claim:

l. In a combined shovel and tamping tool,

. a shovel having a handle, a hollow shank applied to the handle of the shovel and terminating in diverging arms,a latch slidable with relation to the arms and adapted to proj ecttherebetween, a tampinghead rotatably mounted between the said arms and having means for engaging the latch, and a resilientmemberzltor turning the tamping head on its pivot.

2. In a combined shovel and tamping tool, a shovel having a handle, a tamping tool applied thereto consisting of a hollow shank, diverging larms at the outer end of the shank, a pivot supported by the arms, a tamping head rotatably mounted on the pivot, `a latch in the shank projecting from the edge thereof and adapted to hold the tamping head in one position of adjustment, and a resilient memberfor turning the'tamping head on its pivot. Y v

3. ln a combined shovel land tamping tool, ashovel having a handle, a tampingtool appliedthereto consisting'of a hollow shank,

diverging arms at the outer end of the shank,

a pivot supported by the arms, a tamping head rotatably mounted on the pivot, a latch in the shank projecting from the edge thereof and adapted to hold the tamping head in one position of adjustment, a resilient member for 'turning the tamping head on its pivot, a bushing on the pivot connected to the tampinghead, a bushing slidable on the pivotand supporting the tamping head,4 and means for holding one of the bushings in adjusted position with relationto one of the` arms. j y y 4. In a device for tamping sand, a shank having diverging arms andlugs extending,r inwardly from the Sides thereof, a latch slidable in the shank and projecting therefrom, a pivot, a tamping head rotatably mounted on the pivot between the arms and engaging the lugs "for limiting its movement, the said tamping head having .a llatch engaging porT tion whereby the said tamping head is held at one position of adjustment, and means for y partially rotating the tamping head onthe pivot when the latch is released.
